The Genetic Lottery (Futa/F, Futa/F/F, Cumflation, Muscle Futa, Incest, Futadom)

Mona wiped sweat from her brow and jogged towards the gymnasium at her daughter’s school. Her own gym clothes were stuck to her prodigious figure like a second skin and highlighted all the qualities that her friends pointed to when they joked that she had won the genetic lottery - her tall, athletic body, her taut curves and her incredible chest.

Right now her “incredible” chest was threatening to kill off at least two of the four sports bras she was wearing to keep her girls under control.

There was a scream ahead and Mona immediately feared the worst. She picked up the pace and, dark ponytail bobbing, ran deeper into the school grounds.

The noises were harsh, loud and violent; this quiet corridor sounded like an army boot camp.

Alex, Mona’s partner, had been in a few top secret programs for the military before they had met - neither brought the topic up much, but the results had made Alex a dynamite lover: powerful, athletic, responsive and hung like a horse. Mona suspected the treatments were also what had killed Alex in the end - and added further surprises in the genetics of their daughter.

Hurrying along, Mona reflected that she knew everything about her daughter, Gina’s, genetics - the early health issues, the developmental acceleration and the medications she had taken in her childhood. Mona also knew that if her friends had thought she had won the genetic lottery then Gina had won a handful of them... often with interestingly complex results.

Gina was never a handful growing up, but whereas Mona was generally warm and sunny, Gina took after Alex; cooler, quieter and more focused. After Alex passed we had a couple of quiet, sad years getting over our loss, but puberty really changed things in the house.

Alex used to have a huge gym in the basement and we had never moved it out - it was just too big and heavy.

When puberty hit, suddenly Gina was fascinated by it; after Mona had made and set out dinner Gina would come in, quietly thank her mother and wolf down her food before letting Mona lean over and gather all the plates. Even as Mona straightened, Gina would be bolting downstairs to work out.

Gina’s growth was soon off the charts and Mona remembered a time when Gina had regularly torn her clothes stretching for a plate at the table or spooning salad next to her meal - a shopping trip for the biggest, baggiest clothes stopped the ripping, but the after dinner gym sessions continued. Their relationship had gradually distanced until they felt like two pleasant roommates... but no matter what Mona did, Gina seemed to need her distance most of the time.

The noises on the other side of the door at the end of the corridor were strained and hoarse, and Mona bit her lip as she wondered whether or not to go in or call someone to help. Ultimately the door being slightly ajar made her decision for her and she stepped forward to peek in.

“Gina? Honey? I got an alert on my phone from your rape alarm and-“

The door swung open.

Gina was looking down, visibly annoyed at the bag she had evidently stood on accidentally.

To do so, the 6’4” muscular Amazon had to lift the toned thigh of the shuddering, screaming older woman currently mounted on a six inch thick log of flesh that bulged out an otherwise trim and tight belly from a trim landing strip of pubic fur to between heaving, bouncing tits. This manoeuvre didn’t stop Gina’s thick bronzed thighs from driving hard, pistoning her hips and huge shaft roughly, rapidly, into the woman. Even as Mona watched, Gina groaned and seemed to grow - thicker, sharper, veinier.

“Ah fuck,” Gina ground out through between clenched teeth as she looked up at Mona, eyes settling lustily on Mona’s huge tits. There was another surge of muscle growth all over Gina’s body. The muscular teen didn’t even slow as her other hand snaked up under a bouncing armpit to grip her lover-partner-victim by the neck in a standing half-nelson - thick bicep flexing hard to press into the woman’s cheek.

Gina’s eyes met Mona’s and they shared a long look, the teen unashamed and unabashed to be caught powerfucking the school gym coach. Mona saw her lick her lips, and the vicious fucking redoubled. The noise was incredible: the rumble of growing brawn, flesh on flesh, pussy farts and the moans of the cumming, squirting coach.
